BACKGROUND OF THE PRESENT INVENTION Field of the Present Invention

The present invention relates generally to cable managers and related electronic equipment structures, and, in particular, to flexible construction, cable accessories, and doors.

Background

Current and prior cable manager designs generally utilize a U-shaped chassis to which the peripheral parts of the frame are welded, riveted or otherwise attached. The chassis and other parts are usually constructed of sheet metal or injection-molded plastic with discrete patterns for attaching parts and accessories.

Current design methods use sheet metal, wire mesh or plastic parts to provide features for managing and/or supporting cabling and other cabling equipment or for attaching accessories that perform this function. Unfortunately, these features are generally provided in discrete patterns that limit the adjustability and flexibility often desired when managing cabling and other equipment within the manager. Using the features and accessories usually requires hardware and tools for installation, adjustment and/or removal. The chassis construction also makes it difficult to provide gentle cable entry and exit into the manager (i.e., for maintaining bend radii and proper support).

With regard to cable management accessories, current and prior cable manager designs generally utilize a sheet metal frame, sheet metal panel or bracket, or wire mesh with a grid pattern or other type of feature pattern. As a result, accessories are usually installed using hardware and tools and are only adjustable in incremental amounts along a pattern of features or holes within the frame or attachment surface, if at all. Some accessories do have toolless installation methods but are still limited in their application and installation location. Furthermore, much of the space in and around the manager is also wasted as accessories cannot be configured or installed to reach the entire space within the manager.

With regard to doors, particularly for cable managers, it is well known to provide doors that feature hinges at both left and right sides. However, conventional designs generally allow the door to swing on a single bearing surface. Unfortunately, doors that simply swing on a pivot point often sag. When such a door is closed, the bottom edges/surfaces of the door and/or hinge area often make contact with the door frame. As a result, such a door must be pushed, with some effort, back into its closed state. Some door designs address this issue with a ramp-style feature (usually made of plastic or sheet metal) to compensate for sag of the door, which may allow the door to be in an appropriate position for the latch mechanism to engage. However, known door designs maintain a certain level of interference and drag along the bottom of the door as it closes, regardless of whether they must be pushed into place by the user or ramped up into position. In such designs, the bottom of the door or hinge area drags or slides along the frame and creates a frictional force opposite the desired direction of motion.

For the foregoing reasons and/or other reasons, improvements in cable manager structures, accessories, and doors are needed.

DETAILED DESCRIPTION

As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. As should be understood, any embodiment may incorporate only one or a plurality of the above-disclosed aspects of the invention and may further incorporate only one or a plurality of the above-disclosed features. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.

Accordingly, while the present invention is described herein in detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.

Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.

Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.

Regarding applicability of 35 U.S.C. § 112, ¶6, no claim element is intended to be read in accordance with this statutory provision unless the explicit phrase “means for” or “step for” is actually used in such claim element, whereupon this statutory provision is intended to apply in the interpretation of such claim element.

Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”

When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers,” “a picnic basket having crackers without cheese,” and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”

Referring now to the drawings, in which like numerals represent like components throughout the several views, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiment(s) is merely exemplary in nature and is in no way intended to limit the invention, its application, or uses.

FIG. 1 is a front isometric view of a cable manager 10 in accordance with a preferred embodiment of the present invention, and FIG. 2 is a front isometric view of the cable manager 10 of FIG. 1, shown with a cover removed to reveal a backbone assembly 20 and an accessory rod assembly 40. As shown, elements of the cable manager 10 include, or may include, a backbone assembly 20, side walls 12, side wall cable finger units 16, support arms 11, at least one cross bar 17, and a door assembly 18. In some embodiments, the cable manager 10 also includes, or may include, various cable management accessories, which may include one or more accessory rod assemblies 40, one or more half spools 60, one or more repositionable cable finger accessories 70, and/or one or more cable strap/buckle accessories 90, as well as other accessories.

The cable manager 10 of FIGS. 1 and 2 is often used with racks, enclosures, and other equipment to address the needs of cable routing to, from, and around such equipment. In this regard, FIG. 3 is a front isometric view of the cable manager 10 of FIG. 1, shown attached to a two-post mounting rack 13. It will be appreciated, however, that the cable manager 10 may be used with other equipment or in some cases even without any other adjacent equipment. Furthermore, it will be appreciated that many of the features of the cable manager 10 may be incorporated into other IT structures, such as electronic equipment enclosures, and even into some non-IT structures.

It will be also appreciated that many or all of the features of the cable manager 10 of FIGS. 1 and 2 may be incorporated into double-sided cable managers and other structures. For example, FIG. 4A is an isometric view of a double-sided cable manager 210 in accordance with a preferred embodiment of the present invention, and FIG. 4B is an isometric close-up partial view of the double-sided cable manager 210 of FIG. 4A.

FIG. 5 is a front elevation view of the backbone assembly 20 of FIG. 2. As shown therein, the backbone assembly 20 includes a spine member 24 and a plurality of lateral members 23. In at least some embodiments, each spine member 24 and lateral member 23 utilizes an extruded construction, and in at least some of these embodiments, each spine member 24 and lateral member 23 utilize the same cross-section. In this regard, FIG. 6 is an end view of an extrusion 30 used for the spine member 24 and lateral members 23 of FIG. 5. The extrusion 30 includes one or more fastener screw-in channels 31, one or more T-slot channels 32 with internal ledges 35, one or more additional ledges 33, and opposed sides having curvature of a minimum radius 34. The screw-in channels 31 are able to receive and retain screw-in fasteners, while the T-slot channels 32 are able to receive and retain the head of a bolt or other fastener, and/or, in a preferred embodiment, are able to receive and retain a drop-in nut or the like. In the illustrated embodiment (and with further reference to FIG. 7, discussed below), spring nuts 21 are received in the T-slot channels 32 and positioned in their desired locations along such channels 32 with the spring portion of the spring nuts helping to hold them in place via interference fit.

Interconnection between each lateral member 23 and spine member 24 may be facilitated using a mounting bracket 25. In this regard, FIG. 7 is an exploded fragmentary orthogonal view of upper portions of the backbone assembly 20 of FIG. 5. The mounting bracket 25, which may be made of sheet metal, preferably includes a raised lip 22, apertures 26,27, and corresponding fasteners 28,29. The raised lip 22 may help align the bracket 25 along a side of lateral member 23 (and/or along an end of the spine member 24). A first set of fasteners 28 extend through corresponding apertures 26 and into the screw-in channels 31 in the extrusion 30, while a second set of fasteners 29 extend through corresponding apertures 27 and into the spring nuts 21 located in a T-slot channel 32 of the lateral member 23.

By using an extruded construction, the end of a spine member 24 may be positioned at any desired location along the length of the lateral member 23, with adjustment of such position being infinite along the length. Thus, although the spine member 24 in FIG. 5 is shown as being centered between the top and bottom lateral members 23, it will be appreciated that the spine member 24 may be installed or repositioned elsewhere. For example, FIG. 8 is a front elevation view of the backbone assembly 20 of FIG. 2, shown with the spine member 24 disposed toward a side thereof. Furthermore, additional spine members 24 may be added if desired. For example, FIG. 9 is a front elevation view of the backbone assembly 20 of FIG. 8, shown with two spine members 24 installed between the top and bottom lateral members 23.

FIG. 10 is an orthogonal view of a pair of support arms 11 of the cable manager 10 of FIG. 1. The support arms 11 include first and second radiused surfaces 36,37, fittings 38 for connection to the side walls 12, a lateral member interface 39, and a door support 53. The radiused surfaces 36,37 provide proper curvature for cables routed out of the top (or bottom) of the cable manager 10. The lateral member interface 38 may be connected to an end of a lateral member 23 via fasteners (not shown) inserted into the screw-in channels 31 thereof. Details of the door supports 53, which interface with hinge assemblies 130 on the door assembly 18, are provided below.

Advantageously, various embodiments of the cable manager design of the present invention use a combination of extruded, die-cast, injection-molded and sheet-metal parts to provide tracks for attaching accessories and other parts or equipment. This allows “infinite” installation and adjustment of accessories along the track and facilitates the use of clamps or other attachment methods that can eliminate the need for hardware. Features for maintaining bend radii, attaching accessories, doors and other peripheral parts can be integrated into the extruded, die-cast or injection-molded parts of the frame to further increase the functionality and flexibility of the manager when compared to sheet-metal designs. The arms and extrusions further provide gentle cable entry and exit guides to maintain cable bend radii and support. These parts and features can also be applied in a double-sided configuration where cable or equipment management is desired within or around both the front and rear portions of the manager.

FIG. 11 is an enlarged orthogonal view of a portion of the accessory rod assembly 40 of FIG. 2, shown mounted on a spine member 24 of the backbone assembly 20, while FIG. 12 is a front view of the accessory rod assembly 40 of FIG. 11, shown with the end cap 45 removed, and FIG. 13 is an exploded orthogonal view of the accessory rod assembly 40 of FIG. 11, shown in isolation. As shown in FIGS. 11, 12, and 13, the accessory rod assembly 40 includes a base member 41, a knob 42, a rod 43, one or more fasteners 44, and an end cap 45. The knob 42 is threaded into the base member 41 such that a distal end 46 of the threaded portion 47 of the knob 42 can be tightened against a corresponding portion of a spine member 24 or other structure. The threaded portion 48 of the base member 41 has a tapered, angled exterior surface to provide minimum curvature in the area where the knob 42 connects to the base member 41, and a shroud 49 is provided to interface with the underside of the knob 42 so as to shield cables (not shown) from being abraded or being pinched or caught by the knob threads. The function and operation of the knob 42 are described below.

FIG. 14 is a fragmentary top cross-sectional view of the accessory rod assembly 40 and spine member 24 of FIG. 12, taken along line 14-14. As shown therein, the base member 41 is held in place on the spine member 24 via hooks 51 extending from the rear of the base member 41 and by the distal end 46 of the knob 42. The hooks 51 fit around ledges 33,35 of the spine member 24, while the distal end 46 of the knob 42 is pressed against a wall 52 of the T-slot channel 32, thus holding the hooks 51 in place. Although not specifically illustrated, the accessory rod assembly 40 may likewise be mounted on a lateral member 23 of the backbone assembly 20.

Advantageously, the knob 42 facilitates the easy attachment, removal, and/or repositioning of the accessory rod assembly 40 to or on the spine member 24. In this regard, FIG. 15 is a fragmentary top cross-sectional view similar to that of FIG. 14, but with the knob 42 unscrewed to remove the bearing surface of the distal end 46 from the T-slot channel wall 52, and FIG. 16 is a fragmentary top cross-sectional view similar to that of FIG. 15, but with the entire accessory rod assembly 40 shifted sideways to permit removal or movement thereof. Once the accessory rod assembly 40 is in the desired located along the spine member 24 or lateral member 23, it may be installed by reversing the process of FIGS. 14-16 such that the hooks 51 are engaged on the ledges 33,35 and the knob 42 screwed inward until the distal end 46 bears against the T-slot channel wall 52.

In at least some embodiments, the rod 43 utilizes an extruded construction. In this regard, FIG. 17 is a front cross-sectional view of the accessory rod 43 of FIG. 13, taken along line 17-17, shown in isolation. As shown therein, the rod 43 has a generally uniform cross-section and includes a partially cylindrical overall profile, one or more drop-in T-slot channels 54 formed by ledges 57, one or more fastener screw-in channels 55 that may or may not be extensions of the T-slot channels 54, and a plurality of grip channels 56. The fastener screw-in channels 55 are used to attach the rod 43 to the base member 41 via fasteners 44, while the T-slot channels 54 and grip channels 56 may be utilized to attach other structures to the rods 43. The T-slot channels 54 may be utilized conventionally, wherein structures are attached to the rod 43 using fasteners (not shown) where either the head of a fastener, or a threaded nut or similar structure that receives a fastener, is inserted into a T-slot channel 54 and tightened. However, various accessories are known or may be designed to utilize the T-slot channels 54 and/or grip channels 56 in novel ways. Some such examples of various accessories are further described below.

FIG. 18 is an enlarged orthogonal view of a portion of an alternative accessory rod assembly 240, for use in the cable manager 10 of FIG. 2, shown mounted on a spine member 24 of the backbone assembly 20, while FIG. 19 is a front view of the accessory rod assembly 240 of FIG. 18, shown with the end cap 45 removed, and FIG. 20 is an exploded orthogonal view of the accessory rod assembly 240 of FIG. 18, shown in isolation. As shown in FIGS. 18, 19, and 20, the accessory rod assembly 240 includes a base member 241, a cam lever 242, a rod 43, one or more fasteners 44, and an end cap 45. The cam lever 242 includes a cam 246 and a snap feature 247, and the base member 241 includes a snap receptacle 248. The snap feature 247 is installed in, and rotates within, the snap receptacle 248, thus allowing rotation of the cam lever 242 relative to the base member 241. However, other attachment means may be used instead of the snap feature 247 and snap receptacle 248 (so long as they allow rotation). The function and operation of the cam lever 242 are described below.

FIG. 21 is a fragmentary top cross-sectional view of the accessory rod assembly 240 and spine member 24 of FIG. 19, taken along line 21-21. As shown therein, the base member 241 is held in place on the spine member 24 via hooks 251 extending from the rear of the base member 241 and by the cam 246. The hooks 251 fit around ledges 33,35 of the spine member 24, while one or both cam teeth 249 of the cam 246 are pressed against a wall 52 of the T-slot channel 32, thus holding the hooks 251 in place. Although not specifically illustrated, the accessory rod assembly 240 may likewise be mounted on a lateral member 23 of the backbone assembly 20.

Advantageously, the cam lever 242 facilitates the easy attachment, removal, and/or repositioning of the accessory rod assembly 240 to or on the spine member 24. In this regard, FIG. 22 is a fragmentary top cross-sectional view similar to that of FIG. 21, but with the cam lever rotated upward to remove the bearing surface of the cam teeth 249 from the T-slot channel wall 52, and FIG. 23 is a fragmentary top cross-sectional view similar to that of FIG. 22, but with the entire accessory rod assembly 240 shifted sideways to permit removal or movement thereof. Once the accessory rod assembly 240 is in the desired located along the spine member 24 or lateral member 23, it may be installed by reversing the process of FIGS. 21-23 such that the hooks 251 are engaged on the ledges 33,35 and the cam lever 242 rotated until the cam teeth 249 bear against the T-slot channel wall 52.

FIGS. 24 and 25 are a top front isometric view and a front elevation view, respectively, of the half-spool accessory 60 of FIG. 2. This accessory, which may be particularly suitable for routing large numbers of cables within the cable manager 10, includes a central portion 61 for carrying cables, front and rear end flanges 62,63 to help retain cables around or within the central spool portion 61, one or more standoffs 64, a plurality of resilient snaps 65, and one or more finger grips 66. The standoffs 64 (one shown in FIG. 25, but there may be more than one) help position the accessory 60 against the rod 43 of the accessory rod assembly 40, and may include a correspondingly curved surface 67 to provide a better fit against the surface of the rod 43. The resilient snaps 65 retain the accessory 60 on the rod 43, while the finger grips 66 provide a more convenient surface or edge for a user to grasp in order to remove the accessory 60 from the rod 43, all as further described below. The central portion 61 is preferably cylindrical (i.e., forms a portion of a cylinder) and conforms to industry cable bend radius standards. The joints between the central portion 61 and the arcuate flanges 62,63 are preferably also arcuate.

FIGS. 26-28 are front views illustrating the installation of half-spool accessories 60 on a rod 43, for example of the accessory rod assembly 40, which is shown in isolation and in cross-section. In FIG. 26, a first half-spool 60 is shown angled so that the snap(s) 65 along one side thereof can be hooked underneath a ledge 57 of the T-shaped channel 54 of the rod 43. With the first snap(s) 65 positioned, the accessory 60 may be rotated in the direction of the arrow until the snap(s) 65 along the other side are deflected sufficiently to allow them to latch into place around a ledge 57 on the opposite side of the rod 43, as shown in FIG. 27. A second accessory 60 can be installed in the same manner, as shown in FIG. 28, thereby allowing the creation of a nearly-complete cylinder through the combination of the respective central portions 61 in close proximity to one another.

Each half-spool accessory 60 may be removed in at least two ways. First, by gripping the accessory 60, such as via the finger grips 66, and pulling and/or twisting with sufficient force to deflect the snaps 65 along at least one side of the accessory 60, the accessory may be removed by reversing the steps used to attach it. Second, because the rod 43 is of extruded construction, the accessory 60 may be removed by pulling it along the length of the rod 43 until it slips off the end thereof. In some embodiments, the end cap 45 of the accessory rod assembly 40 may be detached to facilitate such removal, while in other embodiments, the shape of the end cap 45 is selected such that the snaps 65 can be pulled off the rod 43 without removal of the end cap 45.

FIGS. 29A and 29B are a top front isometric view and a front elevation view, respectively, of the cable finger accessory 70 of FIG. 2, shown in an open, unclamped state. This accessory 70, which may be particularly suitable as a stable structure to which smaller numbers of cables may be attached in a variety of ways, includes a plurality of semi-arcuate clamp sections 71,72, at least one of which has a finger 73 extending therefrom, that are connected together via a hinge 74 so as to rotate relative to one another. The accessory further includes a clamp mechanism that includes a cam lever link 75 connected to the distal end of one of the clamp sections 71 via another hinge 76, a cam lever 77, including a cam structure 85, connected to the distal end of the cam lever link 75 by a third hinge 78, and a cam trough 79 extending from the distal end of the other clamp section 72. As shown in FIG. 29A, the cam trough 79 preferably includes a notch 84 for receiving the cam lever link 75 as further described below. A latch mechanism, which may for example include a male snap structure 81 on the cam lever 77 and a female snap receptacle 82 on one of the clamp sections 72, is preferably provided to assist in holding the accessory 70 in place. Furthermore, locating ribs or other structures 83 may be provided to help prevent rotation of the accessory 70 when clamped in place. In at least some embodiments, each hinge 74, 76, 78 used a steel hinge spring pin seated in apertures in the respective structures, but other hinge designs and materials may alternatively be utilized. In at least some embodiments, the other components are all made of injection-molded PC/ABS, but other thermoplastic polymers and other materials may additionally or alternatively be utilized.

FIGS. 30-33 are front views illustrating the installation of a cable finger accessory 70 on a rod 43, for example of the accessory rod assembly 40, which is shown in isolation and in cross-section. In FIG. 30, the open, unclamped accessory 70 is shown being positioned on the rod 43. As indicated by the arrows, the accessory 70 may be rotated around the rod 43 until the desired orientation is achieved. The ribs 83 on the first clamp 71 are seated in corresponding grip channels 56 in the rod 43. Subsequent or simultaneous with positioning the accessory 70, the second section can be rotated toward the rod 43 (counterclockwise in FIG. 21) and the cam lever 77 and lever link 75 can be rotated in the opposite direction (clockwise in FIG. 21), as indicated by the arrows. As shown in FIG. 32, once the proximal end of the lever 77 is close enough to the cam trough 79 on the second clamp section 72, the lever link 75 fits into the notch 84 in the cam trough 79, the proximal end of the lever 77 is received in the cam trough 79 itself. With the proximal end of the lever 77 seated in the trough 79, the cam lever 77 may be rotated further toward the second clamp section 78, as shown by the arrow in FIG. 33. Rotation of the cam lever 77 causes the cam structure 85 to rotate within the trough 79, thereby causing camming action by the cam 85 against the trough and forcing the second clamp section 78 against the rod 43. As this happens, the male snap structure 81 is forced into the female snap receptacle 82 until it latches into place. When the lever 77 is fully seated against the second clamp section 72, the clamp section will be pressed against the rod 43 with the locating ribs 83 on the clamp section 72 pressed into the corresponding grip channels 56 in the rod 43. In this state, the cable finger accessory 70 is fully clamped on the rod 43, with the cam structure 85 and latch mechanism holding the accessory 70 around the clamp and the locating ribs 83 preventing the accessory 70 from being further rotated unintentionally. The accessory 70 may then be removed or repositioned by releasing the latch mechanism and loosening the cam lever 77 until the accessory 70 can be moved accordingly.

The cable finger 73 includes a plurality of apertures 167. In the illustrated embodiment, apertures 167 are spaced apart along the length of the cable finger 73, and another aperture 167 is disposed at the distal end the cable finger 73. These apertures 167 may be particularly useful as mounting locations. For example, as described in greater detail below, it is contemplated that the cable finger accessory 70 is equipped to accommodate a cable strap/buckle accessory 90 (or another accessory) at multiple positions along the length of the cable finger 73 (at either side thereof) or at the distal end of the cable finger 73. Further control may be provided by an overhang 171 at the distal end of the cable finger 73, which may help prevent cables or groups of cables from becoming inadvertently tangled or removed by sliding off the distal end of the cable finger 73.

FIG. 34 is a perspective view of the cable strap/buckle accessory 90 of FIG. 2. This accessory 90, which may be particularly suitable as a flexibly-located, quickly-installed structure for holding bundles of cables, includes a buckle 91, a buckle support 92, and a strap 93. The strap 93 may be any conventional strap, such as a hook-and-loop (e.g., Velcro®) strap, zip tie, or the like. FIGS. 35-37 are an exploded top isometric view, an exploded bottom isometric view, and an elevation view, respectively, of a cable strap/buckle accessory 90 of FIG. 2. As shown therein, the buckle 91 includes a base 94 and two raised slots 95. The base 94 is penetrated by a round socket 96, and two coaxial arcuate bosses 97 extend from the bottom of the base 94. The buckle support 92 includes a mounting boss 103 (described below), and a round, resilient snap 98, which is preferably a split snap, that corresponds in size to the socket 96 of the buckle 91. The snap 98 may be snapped or latched into the socket 96 by aligning them and applying sufficient force to deflect the split snap sections inward an amount sufficient to let them pass through the socket 96. Angled surfaces 102 on the top of the snap 98 and similarly-angled surfaces 101 on the underside of the buckle base 94 make this easier. Once the snap 98 penetrates the socket 96 sufficiently, ledges 99 on the underside of the snap sections 98 retain the snap in place. Ridges 177 arranged along side edges of the buckle support 92 provide a surface that is easier to grip or manipulate during installation or use. FIG. 37 is a side elevation view of the buckle 91 and buckle support 92 of FIGS. 34-36, shown in an assembled state.

The accessory 90 may be installed in any of a variety of locations in the cable manager 10 or other location. For example, FIGS. 38A and 38B are top views illustrating the installation of a cable strap/buckle accessory 90 on the spine member 24 of FIG. 2, which is shown in isolation and in cross-section. As perhaps best shown in FIG. 36, the mounting boss 103 is a four-sided rectangular structure with two round corners 104 and two generally square, or right-angle, corners 105. When oriented with the narrow portion of the rectangular mounting boss 103 along the T-slot channel 32 in the spine member 24, the mounting boss 103 may be inserted into the channel 32 (or into a similar structure in a lateral member 23 or other member, or into other channels, openings, or the like), as shown in FIG. 38A. Once inserted, the buckle support 92 may be rotated approximately 90 degrees, preferably in a clockwise direction, such that the wide portion of the rectangular mounting boss 103 is held in place (blocked from removal) by the ledges 35 of the channels 32, as shown in FIG. 38B. Such rotation and subsequent “locking in place” is facilitated by the round corners 104 (which make it easy to turn the buckle support 92 in the preferred direction) and the square corners 105 prevent further rotation and help hold the mounting boss 103 in place. The accessory 90 may then be removed by reversing the direction of rotation of the buckle support 92 in the opposite direction. The round corners 104 of the mounting boss 103 permit such rotation to occur, and when the narrow portion of the mounting boss 103 is once again aligned with the opening of the channel 32, the accessory can be removed.

It will also be appreciated that the round snap 98 and socket 96, as well as coaxial arcuate bosses 97 and trough or slot 100, allow rotation of the buckle 91 relative to the buckle support 92. In some embodiments such rotation can occur whether the buckle support 92 is installed, while in some embodiments, such rotation can occur only when it is installed, and in some embodiments such rotation can occur only when it is not installed. Rotation is possible because the arcuate bosses 97 are coaxial with the socket 96, and the trough or slot 100 is coaxial with the snap 98, such that latching the snap and socket together also causes the arcuate bosses 97 to be located in the trough or slot 100. Once assembled into the state shown in FIG. 37, the buckle 91 may be rotated relative to the buckle support 92 by rotating the buckle base 94 around the snap 98 as the arcuate bosses 97 move within the circular trough or slot 100. An example of such rotation is shown in FIG. 39, which is a fragmentary front view of the accessory 90 and spine member 24 of FIG. 38B. As indicated by the arrow, the buckle 91 may be rotated either clockwise or counterclockwise about the snap 98 of the buckle support 92.

The accessory 90 may also be installed and used in a variety of different locations on the cable finger accessory 70 of FIGS. 29A-33. For example, FIGS. 40A and 40B are front views of a cable strap/buckle accessory 90 being mounted on the cable finger accessory 70 and rod 43 of FIG. 33. As noted previously, the cable finger 73 includes a plurality of apertures 167 spaced apart along the length of the cable finger 73, and another aperture 167 disposed at the distal end the cable finger 73. Each of the apertures 167 can be used to secure a cable strap/buckle accessory 90 to the cable finger accessory 70. Depending on the position and spacing of the apertures 167, some or all of the apertures 167 may be used at once. The apertures 167 are depicted as generally rectangular-shaped apertures, but other shapes are likewise contemplated. In at least some embodiments, a set of locating ribs 169 is disposed adjacent each aperture on one side of the cable finger 73 or the other; these ribs 169 can be used to align a fastener or some other mounting structure in order to facilitate securement of a separate cable strap/buckle accessory 90 to the cable finger accessory 70. In some embodiments, such ribs 169 are provided on both sides (front and rear) of the cable finger 73; in other embodiments, no ribs are provided at all. In at least some embodiments, a cable strap/buckle accessory 90 may be installed on either side of each aperture 167 based on the preference of the user, each aperture 167 may be used only from one side or the other.

When installed on a cable finger accessory 70, the cable strap/buckle accessory 90 makes it easier to retain and manage bundles of cables. In particular, when oriented properly, the mounting boss 103 of the buckle support 92 can be received within one of the apertures 167 of the cable finger 73, as shown in FIG. 40A. Once received within an aperture 167, the mounting boss 103 is rotatable in one direction (preferably clockwise), as shown in FIG. 40B, so that the boss 103 is seated between locating ribs 169 at either side thereof, thereby providing a fixed position for the boss 103 between the ribs 169 and also frictionally clamping the boss 103 and buckle support 92 around the cable finger 73. Removal of the cable strap/buckle accessory 90 can be accomplished by reversing the process so that the mounting boss 103 is aligned with the shape of the aperture 167 to permit it to be removed therefrom. As can be seen in FIG. 29A, apertures 167 are spaced apart along the length of the cable finger 73, and another aperture 167 is disposed at the distal end the cable finger 73. In this regard, it is contemplated that the cable finger accessory 70 is equipped to accommodate a cable strap/buckle accessory 90 (or another accessory) at multiple positions along the length of the cable finger 73 (at either side thereof) or at the distal end of the cable finger 73.

FIGS. 41-43 are perspective views of the cable strap/buckle accessory 90 of FIG. 34 illustrating the attachment of the strap 93 to the buckle 91. As shown in FIG. 41, an end of the strap 93 may be inserted through the two raised slots 95. Once the strap 93 is fully inserted through the slots 95 and positioned as desired, as shown in FIG. 42, the ends may be pulled up, out, back, or the like and closed together, as shown in FIG. 43. Hook-and-loop fasteners or the like may be provided to facilitate the strap ends being fastened together, or other devices may be utilized. Such a strap 93 is very useful for holding a bundle of cables together.

FIG. 44 is a fragmentary perspective view of an upper corner of a cable manager 10 like that shown in FIG. 2 but with various accessories and cable bundles 19 installed therein. The accessories include an accessory rod assembly 40, two cable finger accessories 70, and three cable strap/buckle accessories 90.

Advantageously, various embodiments of the cable manager design of the present invention use a series of extrusions to allow toolless installation, adjustment and removal of cable manager accessories. Accessories can be “infinitely” adjusted along the extrusions so they can reach a much larger portion of the space in and around the manager. The extrusions themselves can also be adjusted within the manager to any desired location. The invention includes several different accessories that may be toollessly installed, adjusted, and removed and corresponding methods with which they may be used. The toolless installation of these accessories improves usability and makes installation, adjustment and removal much faster and easier.

Referring back to FIG. 1, the cable manager 10 includes, in at least some embodiments, a door assembly 18. FIGS. 45-47 are a front elevation view, a rear elevation view, and an enlarged fragmentary rear elevation view, respectively, of the door assembly 18 of FIG. 1. As shown therein, the door assembly 18 includes a door panel 108 having a hinge set along each side and a corresponding latch assembly 110 for each hinge set. As used herein, the term “door panel” refers generally to the portion of the door assembly 18 that swings back and forth relative to the hinges, and may include a plurality of individual panels as well as a variety of other structure. Each hinge set includes a top and bottom hinge assembly 130 that is operationally connected to a respective latch assembly 110. Because each side of the door panel 108 includes its own hinge set and latch assembly 110, the door assembly 18 may be hinged open from either side, and/or the door panel 108 may be removed completely, as shown in FIG. 2. Although shown as part of the cable manager 10, it will be appreciated that the latch assemblies 110 and hinge sets could be used on other cable managers and/or on any variation of electronic equipment (IT) cabinet or enclosure, or at least some other applications, where it is desired to have a door that hinges opens from either side.

FIGS. 48 and 49 are a fragmentary, partially exploded, orthogonal view and a fragmentary, rear cross-sectional view, respectively, of portions of the door panel 108 and latch assemblies 110 of FIGS. 45-47. As shown therein, each latch assembly 110 includes a latch handle 111, a pair of racks 114, a pair of lock rods 115, a pair of compression springs 116, and a gear 117, all contained in a latch housing 113. The latch housing 113 preferably includes two substantially identical halves that are held together with assembly screws 112. The handle 111 is connected to the gear 117 by an assembly screw or other axle 119. The racks 114, which include an upper rack and a lower rack, are disposed on either side of the gear 117 such that the teeth of each rack mesh with the teeth of the gear 117. Rotation of the gear 117 is thus linked to upward and downward movement of the racks 114. To facilitate movement, each rack 114 includes lengthwise ears 120 that ride in tracks 118 formed in both halves of the housing 113. A compression spring 116 is disposed at the proximal end of at least one of the racks 114, while the distal end of each rack 114 is attached to a proximal end of a respective lock rod 115. In operation, movement of the handle 111 turns the gear 117, which in turn effectuates upward and downward movement of the racks 114 in their tracks 118, thereby moving the lock rods 115 up and down.

In at least some embodiments, the door panel 108 and frame are made of sheet metal and steel tube, but other designs and materials may alternatively be utilized. In at least some embodiments, the lock rods 115 are made of aluminum, but other designs and materials may alternatively be utilized. In at least some embodiments, the screws 112,119 and springs 116 are made of steel, but other designs and materials may alternatively be utilized. In at least some embodiments, the other components are all made of injection-molded PC/ABS, but other thermoplastic polymers and other materials may additionally or alternatively be utilized.

FIG. 50 is a fragmentary, partially exploded, orthogonal view of portions of the door panel 108 and the lower hinge assemblies 130 of FIGS. 45-47. Each hinge assembly 130 includes a hinge body 133 that carries a bolt 131 in a central cavity 135. FIG. 51 is a bottom orthogonal view of the lower right hinge body 133 of FIG. 50, and FIG. 52 is a side cross-sectional view of portions of the door panel 108 and one of the lower hinge assemblies 130 of FIG. 50, taken along line 52-52. (It will be appreciated that the hinge body 133 in the lower left-hand corner of FIG. 50 is a mirror image of the hinge body 133 in the lower right-hand corner, and that some of the other components of each hinge assembly 130 are likewise left- or right-handed.) At its proximal end, the bolt 131 receives the distal end of one of the lock rods 115, while at its distal end, the bolt 131 extends out of the opposite end of the hinge body 133. As shown in FIG. 52, the bolt 131 includes an internal pin 143 that extends laterally through a slot 140 in the lock rod 115 such that the lock rod 115 is free to move longitudinally, relative to the bolt 131, over the length of the slot 140. The bolt 131 is biased away from the end of the lock rod 115 by a compression spring 132 disposed between a boss or other structure 141 on the end of the lock rod 115 and another internal pin 142 that extends vertically within the bolt 131.

As perhaps best shown in FIG. 50, the hinge body 133 is fastened to the door panel 108 with assembly screws 136. With particular reference to the arrangement shown in FIG. 52, the bolt 131 has vertical freedom of movement, relative to the hinge body 133, but its downward movement is limited by the interface between a tab 138 at the proximal end of the bolt 131 (the top of the bolt 131 in FIGS. 50 and 52) and the proximal end of the hinge body 133 (the top of the hinge body 133 in FIGS. 50-52), and its upward movement is limited by the interface between the bolt strike 144 and another portion 139 of the hinge body 133. Contact between the bolt tab 138 and the hinge body 133 may be cushioned by a bumper 134 of neoprene or other material in order to reduce noise, physical damage to the parts, and/or the like. Contact between the bolt strike 144 and the hinge body 133 is naturally cushioned by the compression spring 132, but a bumper (not shown) may be utilized here as well. Notably, when the bolt 131 is fully extended as shown in FIG. 52, a hinge pin cavity 145 is defined behind the bolt strike 144, within the end of the central cavity 135 of the hinge body 133.

The door assembly 18 may be mounted between the support arms 11 by mounting the hinge assemblies 130 between upper and lower hinge mounts 160, each of which includes a lifter disk 150 or lifter blank 159 and a lifter nest 162. In this regard, FIG. 53 is a fragmentary, partially-exploded, isometric view of the lower portion of the cable manager 10 of FIG. 2, and FIG. 54 is an enlarged view of portions of the view of FIG. 53, shown with the cross bar 17 removed. As shown therein, a lifter disk 150 and corresponding torsion spring 158 are disposed in a lifter nest 162 at the end of each lower support arm 11. FIGS. 55 and 56 are a side elevation view and a bottom orthogonal view, respectively, of the lifter disk 150 of FIG. 54. (It will be appreciated that the lifter disk 150 in the lower left-hand corner of FIG. 53 is a mirror image of the lifter disk 150 in FIG. 54, and that some of related components are likewise left- or right-handed.) With reference to FIGS. 55 and 56, each lifter disk 150 includes a lower bearing surface 151, a lifting ramp 152, an engagement tooth 153, a raised bearing surface 154, a pair of snap tabs 155, a torsion spring arm catch 156, and a central opening 157. As shown in FIG. 54, the lower bearing surface 151, the lifting ramp 152, the engagement tooth 153, and the raised bearing surface 154 are arranged axially around the central opening 157.

Each lifter nest 162 is disposed in or at the end of a corresponding lower support arm 11. In this regard, FIGS. 57-60 are a fragmentary top isometric view, a fragmentary bottom isometric view, a fragmentary top plan view, and a fragmentary bottom plan view, respectively, of a portion of the distal end of the lower right support arm 11 of FIG. 53. (Although not illustrated, the upper support arms 11 are identical in at least some embodiments, except for left- and right-handedness, in order to simplify manufacturing and reduce unique part count, but the upper support arms may alternatively be uniquely designed.) Arranged in the lifter nest 162 are a hinge pin 161, a snap slot 163 for each snap tab 155 on the lifter disk 150, a torsion spring nest 164, a torsion spring end catch 165, and a snap catch 166 at the end of each snap slot 163. The lifter disk 150 is positioned in the lifter nest 162 such that the hinge pin 161 extends upward through the central opening 157 of the disk 150 and the snap tabs 155 extend through the snap slots 163 and are retained there. The torsion spring 158 is disposed in the torsion spring nest 164 with one end held in the torsion spring end catch 165 (shown as a hole, but other a notch or other structure may be used) and the other end held in the torsion spring arm catch 156 of the lifter disk 150 (visible in FIG. 56). In this arrangement, the lifter disk 150 can rotate around the axis of the hinge pin 161, as limited by the snap tabs 155 in the snap slots 163, but is biased in one direction by the torsion spring 158.

Each lifter disk 150 interfaces with the hinge body 133 and bolt 131 of a respective bottom hinge assembly 130. With particular reference to FIG. 51, the hinge body 133 includes an engagement tooth 147, a lower bearing surface 148, and an upper bearing surface 149. The profile of the engagement tooth 147 defines a lifting ramp 146. The door assembly 18 may be installed on the bottom hinge pins 161 by setting the bottom of the door onto the lower cross bar 17 so that the hinge pins 161 slide up into the hinge pin cavities 145. When the door assembly 18 is in installed and is positioned in its closed state (shown in FIG. 1), and when the lifter disk 150 is in its biased orientation, the lower bearing surface 148 of the hinge body 133 rests on the lower bearing surface 151 of the lifter disk 150 and the upper bearing surface 149 of the hinge body 133 rests on top of the lifting ramp 146/engagement tooth 147 with the lifting ramp 146 of the hinge body 133 in close proximity to the lifting ramp 152 of the lifter disk 150.

Although not illustrated in FIG. 53, a lifter blank 159 is disposed in or at the end of each upper support arm 11. In this regard, FIG. 61 is a bottom isometric view of a lifter blank 159 from one of the upper support arms 11 of FIGS. 1 and 2. The lifter blank 159 includes a bearing surface 172, a central opening 173, and a pair of snap tabs 155. Each lifter blank 159 is preferably disposed, in the orientation shown in FIG. 61, in a respective lifter nest 161 in the end of one of the upper support arms 11 such that the hinge pin 161 extends down through the central opening 173 of the blank 159. With the bottom of the door assembly 18 installed on the lower hinge pins 161, the upper end of the door assembly 18 may be installed on the upper hinge pins 161 by pushing the top of door assembly 18 toward the upper support arms 11 until the bolt strikes 144 make contact with the hinge pins 161. Because of the sloped surface of the bolt strike 144 and the sloped surface 168 on the top of the hinge pins 161, each bolt 131 is driven into its hinge body 133 (downward in the upper hinge assemblies 130), against the bias of the compression spring 132, until the bolt 131 clears the hinge pin 161. At this point, the bolt 131 springs outward again, driven by the compression spring 132, and the hinge pin 161 settles into the hinge pin cavity 145.

Once the door assembly 18 is installed, it may be opened along either side via the latch handle 111. When one of the latch handles 111 is rotated by a user, the corresponding gear 117 is likewise rotated (counterclockwise in FIG. 49), causing the racks 114 to be translated inward against the bias of the compression springs 116. Inward movement of the racks 114 also causes the lock rods 115 on the selected side of the door assembly 18 to be pulled inward. At their distal ends, the lock rod slots 140 pull on the internal pins 143 of the bolts 131, retracting the bolts 131 into the central cavities 135 of the hinge bodies 133. Once the bolts 131 have been retracted a sufficient distance to clear the hinge pins 161, the door assembly 18 can be pulled open and rotated about the hinge assemblies 130 on the opposite side of the door assembly 18.

While the bolts 131 are being retracted along one side of the door assembly 18, the hinge assemblies 130, lifter disks 150, etc. along the other side of the door assembly 18 operate to facilitate rotation of the door assembly 18 about the hinge pins 161 with little interference from the bottom or sill of the door frame (i.e., the cross bar 17, the hinge area, etc). In this regard, FIGS. 62-66 are enlarged fragmentary front elevation views of the lower left corner of the cable manager 10 of FIG. 1 with the door assembly 18 shown in various states of operation. In FIG. 62, the door panel 108 is fully closed, the lifter disk 150 is in its natural state (i.e., rotated to its fullest extent by the torsion spring 158), and the hinge body 133 is resting on the lower bearing surface 151 of the lifter disk 150. As the door panel 108 is opened, the hinge assembly 130 rotates around the hinge pin 161, and the hinge body 133 is forced upward as its lifting ramp 146 makes contact with the lifting ramp 152 of the lifter disk 150, as shown in FIG. 62B. The hinge body 133 continues to be pushed upward by the lifting ramp 152 until it reaches the top thereof, as shown in FIG. 63. After that, further rotation of the door panel 108 moves the hinge body 133 past the engagement tooth 153 of the lifter disk 150 and allows the lower bearing surface 148 of the hinge body 133 to drop down onto the raised bearing surface 154 of the lifter disk 150, as shown in FIG. 64. The hinge body 133 can then be rotated freely on the raised bearing surface 154 of the lifter disk 150, thereby permitting the door panel 108 to be rotated it is fully open, as shown in FIG. 65.

Advantageously, the geometry of the lifting disk 150 and hinge body 133 serves to raise the bottom of the door panel 108 above the cross bar 17 during most of the opening process, thus minimizing or eliminating frictional interference or “rub” between the bottom of the door panel 108 and the cross bar 17. The ramp 152 of the disk 150 pushes the ramp 146 of the hinge body 133 upward, as shown in FIG. 62B, and once the hinge body 133 clears the top of the ramp 152 and drops down to rest on the raised bearing surface 154, the remainder of the opening process is smooth.

Notably, the lifter disk 150 generally remains stationary in its natural state during the entire opening process. However, when the door panel 108 starts to close, the engagement tooth 147 (visible in FIG. 65) of the hinge body 133 eventually makes contact with the engagement tooth 153 of the lifter disk 150 (the state shown in FIG. 64). At this point, the weight of the door panel 108 pushing down on the lifter disk 150 tends to lock the engagement teeth 147,153 together, and further closing movement of the door causes the lifter disk 150 to rotate with the rotation of the door, against the biasing force of the torsion spring). Because the hinge body 133 is carried on the raised bearing surface 154 of the lifter disk 150 as the lifter disk 150 rotates, the bottom of the door panel 108 remains elevated above the cross bar 17 and above the opposite side hinge area, thereby making it easier to close the door panel 180 without frictional interference. Notably, the hinge body 133 and the rest of the hinge assembly 130 remain elevated even when the door panel 108 is fully closed and latched on the opposite side. Only when the bolts 131 are retracted and the hinge assemblies 130 released from the hinge pins 161 (such as when a user wishes to open the door assembly 18 in the opposite direction) is the hinge body 130 released from the engagement tooth 153 of the lifter disk 150, at which point the torsion spring 158 biases the lifter disk 150 back to its natural state.

The latch assemblies 110, hinge assemblies 130, and hinge mounts 160 implement a latch mechanism by using a biased bolt and pin, thereby providing a slam function and keeping the door tightly closed. As described previously, the sloped surface of the bolt strike 144 collides with the sloped surface 168 of the pin 161, thereby forcing the bolt 131 into the hinge body 133 until the end of the bolt 131 clears the top of the pin 161, at which point it springs downward and traps the pin 161 in the hinge pin cavity 145.

Many variations in the design of the door assemblies 18 and the hinge assemblies 130 and corresponding hinge mounts 160. Parts shown herein may be made of specific materials, but could be made of any other material(s) that would be considered suitable or advantageous. In the particular design shown and described herein, the lifter disk 150 rotates relative to the end of the support arm 11, while the lifting ramp 146 is static relative to the hinge body 133. It will be appreciated, however, that these features could be switched, with a lifter disk (or its equivalent) carried by, and rotatable relative to, the hinge assembly or other portion of a door, and a lifting ramp that is mounted on, and static relative to, an end of the support arm.

In the particular design shown and described herein, the lifting function is achieved using a lifter disk, which is implemented as a rotational piece with a ramp and catch feature, wherein “tooth” geometry is provided on the hinge block and the lifter disk such that engagement between the structures rotates the lifter disk with the hinge when the door is closed. This tooth geometry is shown as an angled ramp surface with a radiused profile at the top and bottom of the ramp. In some embodiments, a rubber pad or other cushioning material or features could also be added in that area to soften the drop of the door during engagement of the teeth on the hinge and lifter. Furthermore, in various embodiments, the geometry could be changed in any way that still allows engagement and for the hinge and lifter to catch. Still further, in various embodiments, this function could be performed by any part on the frame or door that engages and disengages based on the current state of the door (opened left, opened right, closed, or the like). Such a part could, in various embodiments, rotate around an axis that is different from the one about which the door rotates, and in other embodiments could slide or otherwise move in a linear or other motion.

In the particular design shown and described herein, the lifter disk 150 is installed during general assembly of the cable manager 10 by simply snapping it into position, but in other embodiments it could also be attached by any other mechanical means that allows it to rotate. Likewise, the hinge assemblies are shown as being attached to the door using assembly screws 136 but could also be attached using another fastening method such as rivets or a snap feature. The hinge assemblies 130 and lifter disks 150 are shown as having left- and right-handed versions, but in other embodiments these elements could be designed to be the same on each side. Similarly, although the left- and right-handed hinge assemblies 130 are the same both top and bottom, in other embodiments they could be different. Still further, although lifter disks 150 are used at the bottom and lifter blanks 159 are used in corresponding locations at the top, in other embodiments they could be designed to be the same both top and bottom.

The latch mechanism shown uses a bolt and pin to allow a slam function and keep the door tightly closed. This also creates the axis around which the door hinges. However, in some embodiments, the latch mechanism could instead have a hinge pin on the door that is drawn up and down by the handle. This would interface with a corresponding hole, slot or feature on the frame to hold in place when engaged.

The latch currently uses a gear and rack assembly which is driven by a latch handle to pull the lock rods and lock bolts toward the center of the door. In some embodiments, however, this part of the design could be modified or replaced with any number of parts that perform the same function such as a simplified latch and lock rod assembly, a cable assembly, or any number of variations of latch assembly designs. The latch handle is shown as a lever on the rear face of the door, extending towards the outside edge. The handle, and corresponding latch assembly, could be placed on any face or edge of the door and be any geometry that allows a user to turn, lift, slide or otherwise move the latch handle to engage and disengage the latch assembly.

Advantageously, various embodiments of the cable manager design of the present invention use a rotating lifter to lift the door as it is opened. After the door is opened past a certain point, the hinge and the lifter engage and the hinge-side of the door is raised. The door is still in the raised state during the closing process, which enables the door to be closed without any interference with the frame or hinge area on the latching side. This allows the door to swing smoothly and freely, when closing, all the way through latch engagement. Subsequently, when the door is opened in the opposite direction, the previously engaged lifter finally returns to its natural position and the door is lifted onto the opposite lifter on the new hinge-side of the door. The invention also includes several aspects of improved functionality compared to previous door hinge designs, including smooth slam-latch capability. Various of these improvements are not limited to use with a cable manager door, but may be used in doors for other electronic equipment structures and even, in some cases, for other structures.

Based on the foregoing information, it will be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application. Many embodiments and adaptations of the present invention other than those specifically described herein, as well as many variations, modifications, and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and the foregoing descriptions thereof, without departing from the substance or scope of the present invention.
